To, all wizomit may concern:

l Be it known-that I, Anios G. Frrz, a citi- 'zen of the United States, and a resident of which are divided ,transversely 'by lines of.

cut 'which permits. the heell part to move upwardly7 and orwardlyrelativ'e to the forepart for the purpose of shortening the last.

The'invention consistsl inmeans 'for locking the parts-of the last in both extended and shortened positions.

In the drawings herewith accompanying, I haveshown several embodiments of my in. vention.

Figure 1 is a longitudinal vertical sectional view of a last havingI one .form oi my invention applied thereto; Fig. 2 is a perspective view 'of the locking device shownin Fig. l; Fig. 3 is .a longitudinal verticalv sectional view of a portion of a last showing a di'erent embodiment ot'my invention; Fig. 4 is an elevation of a portion of a last, parts broken out, showing'a last with my improvement therein in .locked shortened position; Fig. 5' is a longitudinal vertical sectional viewl of a dilierent form of my invention; Fig. 6 is a side elevation, parts broken out, showing a diierent `form of my invention; Fig. 7 is a perspective` view of the locking device shown m Fig. 6.

In said drawings A represents'the fore part, B the heel part, C the line of division of a solid last.

The .adjacent ends of the last are provided with4 kerfs-QD and E respectively in which are pivotally mounted one or more bonding links F. Pivetally mounted in a recess I-I in the heel part is a locking device G. The`upperend of -the locking device is :provided with'a lug I Aadapted to have locking engagement with the fore part ofthe last. y

Ihave shwny'various ways in which. the locking device may engage thet'ore part. vIn Fig. 1 the lug takes into a recess J in the fore part. In F ig.4 3 the lug .takes into the recess, but engages Aa wear pin K inserted just'above the recess. In these cases thelug -`1s S.' htly curved downwardly and .when

move into shortened `relation locks over the top of the l*last holding the parts rigidly in shortened 'relation as shovin Iig.v 4. In these cases a coil lspring L is inserted in the heel part andpresses constantly against the locking device ycausing it to lock automaticallyA andto hold it yieldinglyagainst accidental displacement. To unlock the parts of the last draw the locking device back by pressure on the tngerhold M until the lug is disengaged when the parts ofthe last may/ be moved one relative tothe other. i

' In Fig. 5 I have shown a form of my'inventionJ in whichl the locking device consists of al bar N mounted in arrecess O near the bottom of the last and provided with a spring coil P and with a shoulder@ adapted to engage a stop R on the fore part of the'last. i l

In Figs. 6 and 7 I have shown a locking device having shoulders S adapted to engage pins S projecting beyondthe rear face -ot' the fore part. In this case the lockling bar is provided midway its length jwith va recess V'which gives entrance to the pins S when the heel par`t is curved upwardly relative Ato the fore lpart so that it will permit the` locking device to rest closely-'upon the Arear 'aceor the fore part. In all cases the locking device is'operated manually by pressure upon theiinger-hold. The locking bar is preterably'mounted 'in'the heel part above the bottom and extends across the line o t' division when in operative position.

The advantages of my improved device are that it is'adapted for use in a solid last. It is simple in structure, easily assembled and operates automatically to lock the parts ofthe last together. y v

' Ha-vi'ngthus described my invention and its use'I claim i i 1 In a two part solid last divided transverselyand having a recess extending thereinto from the top, a vertically positionedl rgidlockllg IGVEI' pvotally mounted inthe heel part in said recess and adapted to have 'locking engagement lwith. the fore part said fleverterminating outside the last in a Alinger .hold and means tending constantlyto hold said locking lever in locked engagement.

- 2. In-a two part solid last divided transe.

versely and having a recess extending thereinto from the top, aI vertically positionedl lrigid lockinglever pivotally mounted in the heel part in said recess at a point spaced apart from the bottom and adapted to have locking engagementvwith the fore part-'said lever terminating outside the last in a finger hold and means tending constantly to hold seid locking leverin locked en a ement.

3 n zt two part solid last ldivued. transversely and having areces's extending into :from the top and 'a stop in the Ireargface of 'the fore art,y a vertically ,posit'ined Iig-i6; locking everlpivotally mounted. in the heel part in saidrecess and terminatin outside the last in a `finger ho1d,"a-shou1 er on,

said lever, 'adapted to engage said stop end a spring tending constantly to'forceV said lever 'forward into engagement with Said 'fore part.

In testimony whereof, I hve signed my 15 Y nInl preence of JOHN A. MORRILIQ l H. DUs'roin
